## What is Radix64?

Radix64 turns text, photos, and files into Base64 — and back — entirely on your iPhone, with no upload and no account. It's built for developers who need a data URI for CSS or HTML, anyone decoding a token, or someone who just needs a quick, clean Base64 encode or decode without hunting through a cluttered web tool.

Type or paste on either side and watch the other update instantly — encoding and decoding share one screen, so there's no mode to pick first. Import a photo or file to get its Base64 (or a ready-to-use data: URI), or paste Base64 back in to reconstruct and share the original file.

— WHAT MAKES RADIX64 DIFFERENT —
• One screen, both directions
  Type or paste on either side and the other updates instantly — there's no mode to pick first.
• Standard and URL-safe
  Switch variants and choose whether to keep padding, so the output matches what you're pasting it into.
• Data URI in one tap
  Wrap the result as a data: URI that's ready for CSS, HTML, and email.
• Photos and files, not just text
  Import a photo or file to get its Base64, or paste Base64 back in to reconstruct and share the original file.
• Recent history
  Your recent conversions stay within reach.
• Nothing leaves your iPhone
  Every conversion runs on device, with no upload, no account, and no ads.

— WHO IS RADIX64 FOR? —
• Developers who need a data URI for CSS or HTML
• Anyone decoding a token and checking what's inside
• People who want a quick encode or decode without a cluttered web tool
• Anyone who would rather not paste sensitive data into a website

— PRICING —
Included: live two-way text and Base64 conversion, standard and URL-safe variants with or without padding, one-tap Data URI wrapping, encoding photos and files to Base64 and decoding them back into a file, and recent conversion history.
Radix64 Pro is a one-time in-app purchase — no subscription — and adds batch file and photo conversion plus unlimited, searchable history.
